SPECIFICATION forming part of Letters Patent No. 605,642, dated June 14,1898.

Application filed February 25, 1898. Serial No. 671,592. (No model.)

To all whom it may concern.-

Be it known thatI, EMIL KUBASCH, a subject of the Emperor of Germany,residing at Dresden, in the Kingdom of Saxony, German Empire, haveinvented certain new and useful Improvements in Automatic Window-Closers, of which the following is a specification.

The object of the invention is to provide a window-closer which when astrong wind or storm comes up will automatically close any window leftopen to which it is attached to prevent damage by drafts or strongcurrents of air entering the room or interior to which the'windowbelongs. For this purpose preferably in one or both upper corners of thewindow a fan or a fan-wheel of any number of wings or vanes is arrangedwhich, when set in motion performs the closing of the window.

A special form of construction embodying the principle of the inventionand applied to a window with swinging sashes of the kind usual in mostEuropean countries is shown in Figure 1 whereas Fig. 2 shows theconstruction modified for application to a window with sliding sashes,as usual in America and England.

Referring now to Fig. l, in an upper corner of the Window-casing c isarranged a revolving shaft 1), suitably journaled at d, e, and f, asillustrated, and bearing on its outer end a fan -wheel a, of anypreferred number of wings. On the inner end of said shaft is mounted agrooved wheel or drum g, to which is affixed the end of a rope or chainh. The latter is shown extending downward and passing over a.guide-pulley k on the inner side of the side piece 1' of'the framing,then extending through an aperture in the latter to the outside of thesame and passing over a guide -pulley Z, thereupon again extendingdownward and over a guide-pulley m, after which it is conductedlaterally and over a pulley n, supported by the cross-bar 0, andfastened to an eyelet q of .the swinging sash p.

The drum 9 instead of being on the inner end of the shaft 17 might beplaced on the mid dle portion or outer endof the same, as might also thepulleys be removed from the outside to the inside ofthe window, theexact arrangement of all the details being as preferred in anyparticular case.

It will easily be understood how rotation of the fan in any directionwill cause the window-sash to move from an open to a closed position. Inorder now to prevent a feeble wind or breeze from closing the window, abrake is applied to the shaft 1), preferably adjustable and of anydesired construction. In the drawings a brake is shown composed of alever r, fulcrumed'at one end to the wall or framing of the window,resting on and partially encompassing the shaft 1), and supporting atits other end a pendent rod 8, to which any number of weights t u, 1;may be applied to obtain the desired adjustment of the brake.

A catch or fastener may be provided to hold the sash in its closedposition.

The form and construction of the vanes of the fan-wheel may be of anykind to fulfil their purpose. The fan-Wheel may also be provided with acasing directing the wind in a desired manner. For illustration, in Fig.1 a very simple form of wheel has been chosen. y In the modifioationshown in Fig. 2 the drum 9 is assumed inclosed within a cavity of thewall. The. rope h is passed over but one guide-pulley w and thenfastened to the sliding sash as, so that when the fan on shaft 7) isrotated in either direction this sash will be raised and the windowclosed.

What I now claim as new, and desire to secure by Letters Patent, is

1. In combination with a window, anautomatic device for closing the sameon the arising of a wind comprising a wind-wheel and operatingconnections therefrom to the window-sash whereby the movement of thewindwheel effects the closing of the window, sub stantially asdescribed. I

2. In combination, with a window, a'windwheel, a drum carried by theshaft thereof, a cord adapted to be wound on said drum and operativelyconnected with the window-sash, and a brake to prevent the'too freemovement of said wind-wheel, substantially as described.

In witness whereof I have hereunto set my hand in presence of twowitnesses.

EMIL KUBASOH.
